Attackers might probably exfiltrate delicate recordsdata, manipulate transferred information, implant backdoors, and use the server as a “staging level for ransomware.” The blast radius additional expands in environments the place Serv-U is built-in with Lively Listing or inside storage methods, Seker identified.
